JMA Consulting is pleased to welcome Jon Goldberg as our new Director of Operations effective today.
After a brief stint as a political organizer, Jon spent 13 years working in various capacities at a non-profit legal organization, primarily in IT. In 2010 he co-founded Palante Technology Cooperative and started their CiviCRM department, where he worked for 7 years. Outside of work, Jon can be found engaging in queer community organizing, (dis-)assembling electronics, and training parrots.
"I'm really excited to have Jon join us given his keen appreciation of how to help progressive organizations achieve their missions using CiviCRM. He's got a deep and wide knowledge of CiviCRM. I appreciate how he gives back to the community like through StackExchange, where he is the top ranked CiviCRM contributor," said Joe Murray, President of JMA Consulting and co-author of...Read more
Last week we had a fourth sprint to improve CiviCRM performance at the socialist party.
During this sprint we started with looking at why the screen for adding and editing memberships loaded slow. The issue reported was that it took some time before the end date field jumped from the right side of the screen to the middle of the screen. It turned out that as long as the field was displayed at the right side the screen was still loading. Timing this gave a time of about 18 seconds before the screen was fully loaded.
We discovered a few causes:
- Every request in CiviCRM was also logged in Google Analytics and in Piwik.
- The PHP function getGroupsHierarchy in CRM/Contact/BAO/Group.php took around 900ms to execute (see the issue: https://issues.civicrm.org/jira/browse/CRM-19831)
Since the previous sprint a guy with a lot of database knowledge has done some analysis of the queries and he came up with the following observations. Most queries are build in CRM_Contact_BAO_Query class and that class adds a join on the tables civicrm_group_contact and civicrm_group_contact_cache and a where clause with an or on both tables. See example query below.
SELECT contact_a.id AS contact_id FROM civicrm_contact contact_a LEFT JOIN civicrm_group_contact `civicrm_group_contact-2304` ON (contact_a....Read more
Three weeks ago I wrote about our quest for performance at the Socialist party. This week we had a follow up sprint and I want to thank you for all the comments on that blog.
During this sprint we have been looking into the direction of the amount of groups (+/- 2.700) and whether the amount of groups slowed down the system. We developed a script for deleting a set of groups from all database tables and we deleted around 2.400 groups from the system and we saw that this had an positive impact on the performance.
Before deleting the groups adding a new group took around 14 seconds. After removing 2.400 groups, adding a new group took around 3 seconds. So that gave us a direction in which we could look for a solution.
We also looked what would happened when we delete all contacts who have not a membership from the database and that also had a positive impact but not as huge...Read more
After the socialist party upgraded civicrm to version 4.6 a month ago they are experiencing performance issues. In this blog I will round up our quest for performance improvements. But before that some facts about their installation.
- +/- 350.000 contacts
- +/- 300 users who can access civicrm and see members in their local chapter
- +/- 2700 groups
- There are several campaign websites linked to CiviCRM and one of their successfully campaigns leads to 7500 new contacts per week in the system
- Running on a VPS with 4 CPU cores and 8GB of RAM
- around 40 active extensions
Since yesterday we have added New Relic as a monitoring tool. With New Relic we can monitor and look back in the history. We can also see all the details in each request. So we can analyze the performance.
Someone asked me to post this here - so that he can give it a try!
I've posted the details in a QA format including some of my slides from my CiviCON Lightning Talk on CiviCRM's StackExchange site:
Give it try!
Anyone who has tried to login to their CiviCRM database via their phone knows the feeling: utter helplessness. You would even be forgiven for thinking CiviCRM is actively hostile to the small screen.
This initial experience of the un-initiated CiviCRM user on the phone will probably remain until the eventual adoption of the Bootstrap framework (a CSS framework with built-in mobile/responsive elements).
What may be surprising to many, however, is that CiviCRM today is quite mobile friendly in all the important areas. You just have to put the pieces together.
After a long discussion on the Civi Partners list of the myriad ways CiviCRM developers have been integrating Boostrap into their projects, Allan Dixon started a page documenting them.
The Bootstrap page includes both the...Read more
This weekend the Skvare team attended TexasCamp, the first state-wide DrupalCamp! The Dallas conference attracted users and developers from all over the state to learn and network. Skvare showed community support with a Gold-level sponsorship. Since CiviCRM and Drupal work so well together, we shared some presentations that touched on the intersection of both.
Mark Hanna shared information on a new open-source online learning system powered by CiviCRM and Drupal. This week's release of Skvare's Tin Can compliant Learning Record Store is a Drupal-...Read more
Girls on the Run's mission is to inspire girls to be joyful, healthy and confident using a fun, experience-based curriculum. Teams are paired with coaches who teach valuable life skills over a 24-lesson curriculum that culminates with a 5K run at the end of each season. Every 5K event requires the registration and coordination of thousands of team coaches and over 800 volunteers. Also, as part of sharing their strengths with the community, each Girls on the Run team plans and implements a community service project, which allows them to discover the unimaginable strength that comes from helping others.
With so many volunteers and activities, Girls on the Run St. Louis had a few big questions to solve:
How could they migrate their data away from DonorPerfect, a CRM that was...
There are two powerful modules used in the Drupal world for creating fast custom searches. Search API is a framework which provides an interface for site builders to create custom searches on any entity known to Drupal. It supports several search backends, including Apache Solr and native database search. It has a flexible API so developers can easily extend, customize, and alter aspects of the search process. Many additional contrib modules are available. Using these techniques, searching millions of records becomes fast and efficient.
The Facet API module allows site builders to easily create and manage faceted search interfaces. In addition to the UI components that standard, themers and module developers can build their own widgets, or alter the...Read more
